My take from hundreds if not thousands of miles away while not knowing any details and reading between the lines and subsequently leaping to massive assumptions:

If there are other founders and they are non-technical then part of one or all of their jobs is to keep you from being interrupted. By extension this means that part of their jobs is not interrupting you themselves.

It also means that there should be a clear strategy based on business needs and part of the implementation is prioritizing the product. Android, API and a web app cannot all be equal priority in the immediate term [personally I'd rank them in reverse order because the web app will determine the priorities of the API and the API will make building an Android app easier and if it works as a web app then native mobile isn't all that important to the core idea...but I digress].

So my advice is to ship a web app. Then the company will 'own' whatever users the app attracts and can communicate with them directly through any channel that might work [email, slack, voice calls, snail mail, conferences, cold calls to the customer's address, etc.].

My first drafting job after vo-tech I felt unproductive so for two days I wrote down every time I switched tasks. I showed my boss and we changed things. I was lowest person in the engineering department so I had to get approval to prioritize. For a cofounder the priorities will arise naturally from the work. Just drop what is not urgent and important.

Good luck.
